Surface Sizing to Improve Strength of Recycled Containerboard Webinar

Review of basics of surface sizing by size press including differences between conventional and metered size presses in design and operation and differences in objectives and applications in conventional printing and writing paper and folding carton grades and use for improving dry strength – STFI/SCT and Ring Crush – in recycled linerboard and medium motivated by continuing decline in strength potential of OCC and other recycled fibers.
